AB Salt-tolerant variety of Chuanqiao No.1 and salt-sensitive variety of Chuanqiao No.2 in Tartary buckwheat were used as experimental materials, through treatment of foliar spraying amino acids to study the effect of exogenous amino acids on yield and quality of Tartary buckwheat in non-saline and saline-alkali soil. The results showed that the treatment of amino acids could significantly increase the yield of Tartary buckwheat in saline-alkali soil, under appropriate treatment of amino acids, the content of seed protein, mineral element and rutin in two Tartary buckwheat varieties was significantly increased in non-saline and saline-alkali soil, and that in salt-tolerant Tartary buckwheat variety was increased obviously higher than that in salt-sensitive one. It indicated that the effect of exogenous amino acids on yield and quality varies obviously between the two Tartary buckwheat varieties. In addition, through measuring the soil composition of non-saline and saline-alkali soil, we found that the content of calcium in saline-alkali soil was higher, and that of iron and selenium in saline-alkali soil was significantly lower than that in non-saline one, while that of calcium, iron and selenium of Tartary buckwheat seeds in saline-alkali soil was significantly higher than that in non-saline one, indicating that the Tartary buckwheat in saline-alkali soil shows enrichment in calcium, iron and selenium, and should be more nutritious than that in non-saline one. From the actual usage of amino acids, the amount of amino acid used per hectare is less and the price is low, so it is very suitable for popularization and application in saline-alkali soil.Core IdeasAmino acids treatment could significantly increase the yield of Tartary buckwheat in saline-alkaline soil.Appropriate amino acid treatment could make the Tartary buckwheat in saline-alkali soil more nutritious.This way with low cost is very suitable for popularization and application in saline-alkali soil.
